Air conditioner Bearings are double row angular contact ball bearings. Each air-conditioner bearing consists of one outer ring, one inner ring, rolling elements and cages. Especially, air conditioner bearing requires lower noise and stronger heat resistant specialty. Our air conditioner bearings have been proved to be reliable quality through the usage of customers. Produced with larger ball complement enabling the bearing to withstand greater radial and thrust loads for a given bore size.These 2 series are available with open, shields, seals or snap rings upon request. Sealed bearings may be obtaind with light, standard, or heavy starting torques.
GCr15 grade steel with oxygen content less than 20ppm
Hardness for rings and rollers: 59 - 63HRC
Bearing dimensions and tolerance levels comply with the latest ISO standards

High quality
Extensively used for automobile and motorcycle water pumps, agricultural machines, engineering mining machines
Bearing type: Ball-ball: with two rows of balls; WIB, BWF, WS, WK, 885000 series and Ball-roller: with one row of balls, one row of rollers; WIR, WN, WKH, 665000 series.
water pump bearing is the most important part of the water pump. Because the high speed of revolution, usually it reaches 10000rpm/min, it requires the high-load ability of water pump bearing. And only this can keep the life of bearing under the high speed revolution.
Water pump bearings are primarily used in automotive water pumps, basically consisting of standard double row bearings.
Production range: include standard needle roller bearings, thrust ball bearings,taper roller bearings, water pump bearings, tension pulleys and clutches.
